To all whom it may concern: I

Be it known that I, SWAN A. NELSON, a

citizen of the United States, residing at Tun-- nelhill, in the countyof Cambria and State of Pennsylvania, have invented certain new anduseful Improvements in Adjustable Screen-Doors, of which the followingis a specification.

My .invention relates to screen doors and more particularly to that typeof screen door which it is possible to adjust for various sizes of dooropenings.

One object of the present invention is to provide a screen. door of theabove mentioned character which consists of a plurality of parts adaptedto be interfitted with each other and secured in such a manner as toform a rectan lar frame adapted to receive the wire mesh Another objectof the present invention resides in providing a door of the abovementioned character which is cheap to manufacture dueto the fact that,by reason of the employment of peculiar bracing means, the materialsemployed may be exceptionally light and yet the door will be unusuallystrong.

A further object resides in the provision of means carried by one edgeof the door and adjustable with the frame and providing means .to mountthe door in the door opening without screws.

With the above and other objects in view, I will now proceed to describethe specific embodiment of the present invention, which, by way ofillustration only, I have shown in the annexed drawings forming a partherewith and wherein:

Figure 1 is a plan view of the completed door.

Fig. 2 is a sectional of Fig. 1, and

Fig. 3 is a sectional view on the line 33 of Fig. 1.

In detail:

The door comprises a frame A of rectangular construction and whichconsists of four right angle members 1, 2, 3 and 4: having legs 5, 6, 7,8, 9, 10, 11 and 12, respectively. Considering first the portion 1, theleg 5 thereof has a plain end provided with a drill hole adapted toreceive a screw 13 and the leg 6 thereof is provided at its end with theoverturned flanges 14 which form a channel.

The portion 2 comprises the legs 7 and 8,

view on the line 2- 2 both of which are plain and each end of which isprovided with screws 15 and 16, respectively.

The portion 3 is provided with the two .legs 9 and 10, the former ofwhich has flanges 17 turned over to form a channel and the latter ofwhich is plain and provided with a screw 18. 1'

The portion 4 comprises legs 11 and 12, the former of which is providedwith flanges 19 turned over to form a channel and the latter of which isprovidedwith. flanges 20 turned over to form a channel. These fourportions are assembled by disposing the plain ends of the various legsin the channels of the flanged ends and tightening the screws 13, 15, 16and 18 so that the said portions are held in any adjusted assembled.

relation with respect to each other. It will be evident that byloosening the screws hereinbefore enumerated, the, width and length ofthe door frame may be varied to suit the size of the door opening.Disposed around the inner periphery of the frame are a num ber of screwholes or the like 21 which are provided to receive screws 22 which holdthe wire mesh or fabric 23 to the frame. Diagonally across the frame andattached as shown at 24 to the corners of the portions 2 and 4 of theframe are two rods 25 each-having adjacent threaded portions 26oppositely threaded and receiving the turnbuckle 27 so that when theframe is assembled, this turnbuckle may be tightened and the doormay bebraced by the rods 25. Transversely of the door and connecting oppositesides 'of the frame are the telescoping braces 28 each of which consistsof two members 29 and 30 in telescoping relation and secured to the doorframe as shown at 31 by any suitable means.

. Along one edge of the door are two rods 32 and 33, the adjacent endsof such rods being oppositely threaded as shown at 35 to provide for aturnbuckle 36 and when the width of thedoor is varied, this memberextending along one edge thereof maybe also adjusted. This rod carriesthe leaves 37 which secure the said door to the casing tudinally of thefixed position of the hinges to permit it to swing easily and free ofthe threshold or top place of the door frame.

To locate the door in a doorway the door is held in the proper positionand the turnbuckle 36 is moved so as to expand the feet A and B againstpartitions C and D respectively. In this way the doorway is secured inplace without screws.

It will be seen from the foregoing that I have provided a screen doorframe which is easily manufactured, assembled and applied and, while Ihave herein shown one specific embodiment of the present invention it isnevertheless to be understood that, in practice, I may resort to suchpractical modifications and variations of the present design as fallwithin the scope of my invention as defined in the appended claims.

I claim:

1. The combination in a screen door of a plurality of frame memberstelescopically saiil frame, and hinge plates carried by said ro 3. In adoor, a frame having longitudinally and laterally adjustable sides andends, respectively, a diagonally disposed longitudinally adjustable rodcarried by said frame, a side rod secured at its ends to the upper andlower ends of said frame, means for adjusting said rod longitudinally,hinge plates pivotally carried by said rod, and stops on said rod forlimiting the longitudinal movement of said plates.

4:. A door comprising a plurality of sections each having angularlydisposed bars, sockets on the ends of certain of said bars to slidablyreceive the ends of the bars of the next adjacent sections, screws forholding said sections in a'djusted positions, a longitudinallyadjustable rod disposed diagonally across said door and being connectedat its ends to certain of said sections, a longitudinally adjustable rodsecured to one side of said door, and hinge leaves carried by said rod.

In. testimony whereof I afiix my signature in presence of two witnesses.

SWAN ALLEN NELSON.
